Choose a mark for what is there and how far
it is from Manila. The dashed line is the second flight, measured straight through
the air — the aircraft does roughly that.
from Manila, in a straight line.
Every mark sits at its real coordinates and every distance is
computed from them. Casa Marikit is invented for this design study —
the airports, the town and the island are not. No coastline, road or runway is drawn,
because that geometry cannot be sourced offline and guessing it would be a lie on a
page about getting somewhere.
